On the day she hanged herself she had taken a phone call from the television chef and food campaigner in which they talked about her future in his business.

Andrew Forrester, who had known her for six years, was with her when Mr Fearnley-Whittingstall rang, and said in a statement read to the inquest in Exeter: "She stated that no one was giving her a straight answer."

Miss Corbin's father, Hugh, who found his daughter's body, said she had been suffering from depression and anxiety.

She had left a note stating she intended to kill herself.

Exeter and Greater Devon deputy coroner Darren Salter ruled that she took her own life. "Given the evidence together, of course, with the note, I'm satisfied about that, that it was her intent," he said.
